valve rocker arm replacement

[4doorVIP]

Hello, could I please have some advice on how to replace a single rocker arm on our 3A-C rocker shaft?
I broke valve #5 rocker arm by over tightening the nut (do'h!!!!)

I believe the part no is 13811‑15010

Here's some pictures :[

yo, see my post on your other thread.

it is easy, you just remove the rocker arm shaft (some 10 mm bolts), and than you slide the rocker arms off the shaft. do you have a replacement handy? I have some extras you can have if you need one.
